550xp sux

[MaddBomber]

I own a 2018 550xp Mk1. It refuses to idle, constantly runs rich and bogs in the cut.
According to the dealer, it has 21 hours on it.
It has been to certified repair shops 4 times for a total of 17 weeks. No difference in its lack of performance.
It starts fine, but loads up and dies. It has had a carburetor, ignition/coil, flywheel, muffler, and decomp replaced by Husqvarna. Plus, passed repeated vacuum & pressure tests. Excellent compression of 191psi cold, 168psi hot. New OEM plug, no spark arrestor.
Still will not hold an idle, and randomly bogs hard in the cut
The dealer repeatedly told me that it's fine and just needs to break in.
I have a same year 362c that never has a problem, and a newer 462c that has considerably less hours and runs flawlessly.
Could there be a bad cylinder cast? I can't believe it would be two bad carbs, and/or two bad coils... With exactly the same symptoms.
I really want to like this saw. It's so comfortable, smooth, and handy... But it's a damn $700 boat anchor.

I was thinking a crank seal leak (yay husky 5 series) that only manifested at temperature, but even cold it will not idle.

My buddies mark 2 550 was doing that, one crank bearing is gone.
He's pissed the saw has about 10 hours on it.

I had a lemon also. I dumped it cheap and bought a Mark II.

Husqvarna has all but dried up and blown away from my area. The last dealer within 40 miles has just lost husky.. they're strictly Stihl and Echo now.
I don't necessarily like the feel of the 261c so I'll probably resurrect my old 026 or get a decent 346xp.
Husqvarna has really crapped themselves with the 5 series. Such an epic fall from grace.

Not a necessity right now, but I'll own another 346xp before it's all said and done. Doubtful on the Stihls.
